The word on the street today is that Scott Brison has been busy trying to engineer a vote of non confidence in the government before Jim Flaherty is even allowed to read his budget on March 22nd. These rumours began to spread the day after Jack Layton had major hip surgery, which should take him at least a few weeks to recover from. Perhaps the timing of the Liberal accelerated election plans and Jack's surgery is just a coincidence. It seems too callous, even for Iggy, to fast-track an advantageous quick election because of the health of an opponent.
The more plausible scenario is that the Liberals may be worried that Canadians might like the budget. They have committed to voting against it regardless of what's in it, and it could be a great budget. The upside of withdrawing support for a budget months before it is even written is that you force the other opposition parties to be seen as the ones responsible of either forcing an election or propping up the Harper government. There is however a downside, and that it boxes you into a corner if the budget turns out to be a good one. It also withdraws you as a negotiator and thus contributor to the legislation.
Today on CBC radio the guy was saying that the Liberals need Milliken to rule on Scotty's request very quickly, as parliament won't be sitting the week before the budget. My message to the Speaker is wait until after the budget. It could very well contain detailed outlines of the prison infrastructure spending, which would make Mr. Brison's current quest for fire moot.
